To all whom it may concern Be it known that I, VILLIAM J. DAVIS, Jr., acitizen of the United States, and resident of Chicago, Illinois, haveinvented a certain new and useful Improvement in Inverted Lamps, setforth in the following specification.

My invention consists of an improvement in which a lamp is disposedunder a hood, the under surface of which is adapted to be used as areflector, and which hood is imposed upon a stand which is formed ofwoven wire, or other open work material, the object of my inventionbeing to procure a shaded light of such an area of illumination as to beadapted to furnish light forcleaning and other work on floors; the hoodbeing adapted to avoid blinding the eyes of the worker and to direct thegreater volume of light to the exact place where required, and the standbeing of such a height as to permit the worker to carryit handily aboutand thus avoid the useless lighting of the surrounding overhead space.

My invention is illustrated by the accompanying drawing in which similarletters refer to like parts throughout the several views, namely:

Figure 1 is a. side elevation, in use. Fig. 2 is a vertical section onthe lie 22 of Fig. 3. Fig. 3 is a plan View of the rigid hood asattached. Fig. 4 is a side elevation showing the fiddle attachment inoperation. Fig. 5 is a vertical section on the line 5-5. Fig. 6 is aplan view as attached with the fiddle.

In detail, the stand a is formed of woven wire Z) and is of conicalshape so as to provide an ample base a and tapers upward a suitableheight to a sutliciently small diameter at the binding band cl toreceive the hood 0 which in Figs. 1, 2 and 3 is rigidly fixed to theband (Z and forms a closure at the apex of the stand. Within the hood 6is preferably an ordinary incandescent lamp f the contact end 9 of whichprojects upward through the hood 6 a sufficient distance to receive thecontact H of the lead line i, the running end j of which connects withsome convenient electric light fixture. The slack of the lead line iswound about the stand a to suit the convenience of the worker as shownin Figs. 1 and l. The inner surface of the hood forms a back orreflector for the lamp. The device is handled by the Worker by means ofa bail 70 which is rigidly fixed to the top of the hood 0.

In the modification as shown by Figs. 4:, 5 and 6 the hood 6 ismovablyconnected to the band (Z by means of the trunnions n n, and bymeans of the band 0 which is movably connected to the band on by meansof trunnions 7) p. The trunnions n n and p may consist of rivets or ofbolts, and preferably so tensioned as to provide suflicient frictionalcontact between the bands (Z and m at the trunnions n n and between thebands m and 0 at the trunnions p p, to hold the fiddle in any positiondesired by the worker so that the hood 6 may be tilted and the lightdirected in any desired direction while at the same time the stand aremains in an upright position on the floor or if preferred thetrunnions may be so loosely attached that no matter how the stand a maybe inclined the hood 6 will automatically maintain a horizontalposition.

In the course of my experiments I made a stand in the form of apractically perfect cone, out of woven wire, and attached anincandescent lamp within the apex, but I found that it was preferable toattach a hood in the form here shown, which better shades the light fromthe workers eyes and which can be adapted to serve as a reflector ifdesired; By using the fiddle attachment the hood may be tilted toilluminate passages or other inaccessible regions to suit theconvenience of the worker.

The stand may be made of any open work material or construction so longas the clownward and out-ward direction of the light is not undulyobstructed or shaded, but for reasons of economy I prefer woven wire ofsubstantial weight and of say about an inch mesh, the same being stockmaterial and therefore easily available.

It is obvious that the various common forms of lighting may be adaptedto my stand and hood, but for adaptability, econfor tilting saidhood,-'siibstantia1iy as do omy and safety, I prefer the electric lamp.scribed. 10' I claim, Witness my signature this 27th day of.
